JPH08273637A - Label for lead-acid battery - Google Patents

Abstract

PURPOSE: To provide a label for a lead-acid battery by which writing-in to the label can be easily performed even by a pencil and a ball-point pen and the written-in content is not erased by arranging fine recesses-projections on a surface of a protective film of the label. CONSTITUTION: This label for a lead-acid battery is composed of a key sheet 1 where an adhesice 2 is applied to the reverse and a protective film 3 where an adhesive 2 is applied to the reverse, and a surface of the key sheet 1 is coated with the protective film 3. Fine recesses-projections 4 are arranged on a surface of the protective film 3, and the surface is formed in a pear skin shape. A pencil and a ball-point pen do not slip on a surface of the film by these fine recesses-projections, and writing-in can be easily performed. Since graphite and ink enter a recessed part and are held, the written-in content is not erased by wiping-out of the surface.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a label attached to the surface of a battery case or a lid of a lead storage battery, and more particularly to a label on which information such as the date and time when the lead storage battery is used and the expiration date can be written.

[0002]

2. Description of the Related Art Labels (hereinafter referred to as storage battery labels) attached to the surface of a battery case or a lid of a lead storage battery must have corrosion resistance to dilute sulfuric acid which is an electrolyte of the lead storage battery.

Hereinafter, a conventionally used storage battery label will be described. FIG. 2 is a sectional view of a conventional storage battery label, and FIG. 3 is a plan view thereof. The mount 1 made of synthetic paper on which precautions for use and the like are printed is coated with the adhesive 2 on the back surface and attached to the battery case or the lid. A protective film 3 having a smooth surface and acid resistance is coated on the surface of the mount 1 via an adhesive 2.

As shown in FIG. 3, numbers are printed in advance on the mount 1, and a pair of semicircular slits 5 are provided around the numbers. By peeling off the part of the number corresponding to the year and month from the label for the storage battery, information such as the start of use was recorded.

[0005]

Since the mount 1 is covered with the protective film 3 having a smooth surface, the pencil or the ballpoint pen slips, and it is difficult to write information such as the date of attachment and the expiration date on the label surface. Moreover, there is a problem that the written matter can be easily wiped off.

On the other hand, although the corresponding numeral portion is peeled off for recording the information, there is also a problem that this peeling is difficult. Further, a large number of pairs of semicircular slits 5 are required, and the punching die for forming such a label has a complicated structure and is expensive.

An object of the present invention is to provide a label for a lead storage battery, which can be easily written on a label with a pencil or a ballpoint pen and whose written contents cannot be erased.

[0008]

DISCLOSURE OF THE INVENTION The present invention is a lead acid battery comprising a backing sheet having an adhesive applied on its back surface and a protective film having an adhesive agent applied on its back surface, the backing surface being coated with the protective film. In the label for use, the protective film is formed in a pear-skin shape by providing fine irregularities on the surface.

[0009]

With the fine irregularities formed on the surface of the protective film, a pencil or a ballpoint pen does not slip on the surface of the film, and writing can be performed easily. Further, since the graphite and the ink enter and are retained in the concave portions, the written contents are not erased when the surface is wiped.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of a label for a storage battery according to the present invention.

An adhesive 2 is provided on the back surface of the mount 1 made of synthetic paper.
Has been applied. On the other hand, the surface of the mount 1 is coated with an adhesive 2 with a protective film 3 having fine irregularities 4. The protective film 3 is made of polypropylene having excellent acid resistance.

Table 1 shows the writing characteristics with a pencil, a ballpoint pen and an oil-based ink for the label for a storage battery of the present invention using a protective film having fine irregularities and the conventional label for a storage battery.

[0013]

[Table 1]

As is clear from Table 1, the lead-acid battery label of the present invention can favorably write on the surface of the protective film with any writing instrument.

Next, the change of the display state by wiping off the contents written by the writing instrument was examined. The wiping methods were blank wiping, water wiping and dilute sulfuric acid wiping. The results are shown in Table 2.

[0016]

[Table 2]

With the lead-acid battery label according to the present invention, the contents written on the surface of the protective film are not wiped off, and an excellent effect can be obtained in this respect as well.

[0018]

As described above, according to the present invention, by providing fine irregularities on the surface of the protective film, writing can be easily performed even with a pencil or a ballpoint pen. Further, since graphite and ink enter the concave portions, it is possible to realize a lead-acid battery label in which written contents are not erased by wiping.
